Based on the security foundation of asset storage, Coinex has adopted an industry-leading cold and hot wallet isolation architecture, storing over 98% of users’ digital assets in a completely offline cold wallet system. These cold wallet private keys are managed through distributed multi-signature technology. At least two of the three private key fragments or three of the five must work together to authorize transactions, effectively preventing single point of failure and internal malpractice risks. This standard is highly consistent with the cryptocurrency custody framework requirements issued by the New York State Department of Financial Services (NYDFS) in 2020. The platform’s hot wallet retains only about 2% of assets to meet daily withdrawal needs and ensures a minimized balance by dynamically adjusting thresholds. Even in extreme situations, it can keep potential losses within an extremely low percentage of total assets.
Account access and operational security form the second solid line of defense. Coinex forces users to enable two-factor authentication (2FA), supports Google Authenticator and hardware security keys, reducing the success rate of unauthorized logins to nearly zero. Its system will intercept in real time any new device login or abnormal location access (for example, initiated from an IP address over 1,000 kilometers apart within one hour), and trigger dual authentication alerts via email and text message. The risk control strategy for withdrawals is particularly strict. The whitelist address set by the user needs to go through a lock period of 24 to 48 hours after the first addition. Any large withdrawal (such as a single transaction exceeding 10 BTC equivalent) requires multi-level manual review. These measures effectively prevented large-scale phishing attacks similar to those that occurred in 2022, which caused an average loss of $90,000 per victim.
The background risk control system of the platform is an intelligent monitoring network that operates continuously for 7×24 hours. It can analyze over 100,000 transaction behaviors per second and build user behavior models through hundreds of risk parameters such as login frequency, device fingerprints, transaction rate, and amount deviation. Once an abnormal operation deviating from the benchmark model by more than 3 standard deviations is detected, the system will automatically freeze the relevant session and conduct a deep audit within 100 milliseconds. For instance, when a sudden large transfer to a new address is detected and this address has a correlation degree of more than 0.8 with a known dark web address, the system will automatically suspend the transaction. This automated risk control solution draws on the machine learning models used by traditional banks in preventing credit card fraud, and the false alarm rate has been optimized to less than 0.1%.
At the infrastructure and compliance level, Coinex deplores its core servers in Tier-4 data centers with biometric access control and uses full-site SSL encryption to ensure a data transmission strength of 256 bits. The platform regularly invites top security teams like SlowMist Technology to conduct penetration tests, and conducts at least four comprehensive audits each year. The repair rate of discovered vulnerabilities remains at 100%. In compliance with international anti-money laundering (AML) standards, its KYT (Know Your Transactions) system scans on-chain transactions in real time and monitors the flow of suspicious funds. As shown in a certain industry stress test report in 2023, Coinex successfully withheld the traffic impact of over 5 million requests per second at its peak when dealing with simulated DDoS attacks, maintaining a service availability of over 99.99%.
To build a deep defense ecosystem, Coinex has established a bug bounty program with a total amount exceeding one million US dollars, encouraging global white-hat hackers to proactively discover and report potential vulnerabilities. Depending on the severity level of the vulnerability, the maximum reward for a single instance can reach up to 50,000 US dollars. This strategy draws on the outstanding security practices of Google and Microsoft, transforming external security researchers into powerful defense Allies. Through this proactive, multi-level, and dynamically evolving security framework, Coinex has maintained a record of zero loss of user assets since its establishment, which has earned it solid trust in the uncertain digital asset world. The annual growth rate of its security budget has also consistently exceeded the industry average.
